ABRAHAML. GARVER, OF ROARING SPRING, PENNSYLVANIA.

MACHINE FOR SECURING BACKING-STRIPS TO AND FOLDING BOOKS.

SPECIFICATION forming part of Letters Patent No. 509,215, dated November 21, 1893.

Application filed August 12, 1893- Serial No. 482,962. (NomodeL) To all whom it may concern.-

Be it known that I, ABRAHAM L. GARVER, a citizen of the United States, and a resident of Roaring Spring, in the county of Blair and State of Pennsylvania, have invented certain new and useful Improvements in Machines for SecuringBacking-Stripsto and FoldingBooks; and I do declare the following to be a full, clear, and exact description of the invention, such as willenable others skilledin" the art to which it appertains to make and use the same, reference being had to the accompanying drawings,a nd to letters of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a vertical longitudinal section. Fig. 2 is a top plan view. Fig. 3 is a vertical transverse section taken on line a: as, Fig. 2. Fig. 4 is a vertical trans verse section taken on line y. y. Fig. 2 and Fig. 5 is a sectional detail of the disks, &c.

This invention is designed to provide a simple, practical and eflicient machine by means of which tape, or other suitable backing strips may be secured to books, such as memorandum, pass, blank, account, and other books having flexible covers; and which will also after theback or strip has been secured in place, neatly fold the book into its finished form.

With these objects in view, the invention consists in the novel construction and combination of parts all as hereinafter described and pointed out in the accompanying claims.

Referring to the accompanying drawings, illustrating the invention, the letter A designates an extended horizontal table supported in any suitable manner. Working upon said table is an endless feed apron B, carried by rollers a, a, driven by suitable gear, as indicated.

O, O designate a pair of transverse rollers journaled in proper relation to the table A, and between which the upper, or working portion of the apron B passes. The upper roller 0 is made capable of a vertical adjustment in its bearings toward and away from the lower stationary roller 0, as indicated at b in order to allow the proper adjustment for books of difierent thicknesses.

D is a frame supported on the table A, over the apron B, and E is a reel journaled in said frame transversely of the table, said reel carrying the tape or other suitable material E from which the backing strips are made. Also supported on said frame D is a glue pot F, which is heated bysteam or hot water in a tank F, the steamer water entering and leaving said tank by the pipes c, c; or other suitable means may be employed to heat the glue pot. Turning in said glue pot is a wheel G having a broad periphery overlwhich passes the tape E from the reel 'E, receiving therefrom in its passage a sufficient coating of the glue, or other adhesive material. The tape then passes over the table to a point near the farther end thereof, where it passes over pulleys d, 01, carried by standards d, and thence back and over a pulley 01 supported by an arm of the frame D, thence rearwardly and downwardly over a pulley d at the rear of the reel E, and thence downwardly and forwardly and between the rollers O, O, at the central portion thereof. The pulleys 01,01, d and d are so arranged that only the unglued surface of the tape contacts therewith.

D is an adjustable scraper for removing excess of glue from the glue wheel G. The books in their flattened condition, as seen in Fig. 3 are placed on the apron B underneath the tape E, and are successively fed through between the rollers O, C, which press the tape down thereon and cause it to firmly adhere. As the books leave these rollers the tape is cut at the proper point by an operator, or by suitable mechanical cutting devices, not

shown, and are carried along and onto a second endless, traveling apron H, guides h being provided all along the table to prevent any lateral travel of the books from the time they are fed onto the apron until they reach the folding mechanism presently to be described.

I, I are a second pair of transverse rollers between which the books are carried by the apron H, and which act to again set the tape to the book should it have been loosened somewhat at the end by the cutting, which is frequently the case. Shortly after leaving these rollers, the books pass from the forward portion of the apron H, onto an endless travelin'g cord J, which passes around the forward carrying roll i of the apron H, in a grooved ICO boss j at the central portion thereof, and also around the grooved periphery of a large rotary disk K journaled near the forward end of the table. In order not to interfere with this cord, the apron H is divided longitudinally into two parts whose inner edges are separated from each other a short distance, as seen at k.

J ournaled transversely over the disk K is a shaft L which at its central portion carries two disks L, L, an axial projection lof one of said disks engaging a corresponding socket Z in the other, and forming between said disks an annular space L which receives the peripheral portion of the disk K. The adjacent edges of said disks are beveled outwardly as shown at m, and each disk has in its periphery a groove m. Running around in said grooves m, and around the upper rollers I are two endless cords or belts M, M, one a short distance to each side of and a little above the cord J, and acting to hold the book down upon said cord so that it will be carried along thereby, while at the same time leaving the lateral portions of the book unsupported from below so that it may readily fold. The cord J is supported bya longitudinal bar N, hav-' ing therein a groovensufticiently deep to receiyle about one-half the diameter of the said cor Between the rollers I, I and the disk K are two small central wheels P and P, situated directly over the cord J, which press the book down onto the said cord, and hold it in the proper position to enter between the disk K, and. the folding disks L, L. The first wheel P has a plain periphery, but the second wheel P has aV-shaped groove th erein which presses against the central part of the book, and commences the fold, which is completed by the disks L, L and K as will be readily seen.

The bar N, which supports the cord J, is of somewhat inverted V-shape in cross-section, the groove 'n beingin the angle thereof. This form is preferred as it offers no resistance to the folding.

The wheels P, P are carried by transverse shafts journaled in bearings R which are capable of a vertical adjustment toward and away from the table, springs a" being provided in connection therewith to render them sufficiently yielding. The adjustment is effected by means of screwsS acting on the said bearings. The upper roll Iis also made capable of a vertical adjustment as indicated, and the two disks L, L are capable of a lateral adjustment toward and away from each other on the shaft by means of nuts 3.

It will be observed that the tape carrying devices before described are so arranged that a considerable length of tape is constantly kept unwound, so that some time elapses after any portion of the-tape leaves the reel before it is applied to the book. The purpose of this arrangement is to give the glue time to set somewhat so that it will firmly adhere to the scribed, the combination book and not be stripped therefrom by the rolls as would otherwise occur.

Suitable gear connections are driving the various parts.

Having thus described my invention, what I believe to be new, and desire to secure by Letters Patent, is the following:
